Radiation Image Display Preview Generation for Real-Time Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Radiation image display apparatuses are inconvenient for photographers during moving image photography as they require waiting for the generation of a main image before allowing image adjustments or frame-by-frame viewing, leading to delayed image checks and increased burden on patients.
Innovation Solution
A radiation image display apparatus that generates a moving image preview based on multiple frames, performs reproduction control, and allows image adjustments during the preview display, enabling real-time image checking without waiting for the main image to be generated.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the radiation image display apparatus generates a moving image as a main image before allowing image adjustments, then the main image quality is ensured, but the waiting time for photographers and patients increases
Solution Approach 1:
The patent divides the image processing into two segments: a preview image generated quickly for immediate display and adjustment, and a main image generated subsequently for final use. This segmentation allows the preview to be displayed without waiting for the complete main image processing, thereby reducing waiting time while maintaining the option to generate high-quality main images when needed.
Solution Approach 2:
The patent applies partial action by generating a preview image that contains sufficient information for initial assessment and adjustment, without completing the full main image processing. This partial processing enables photographers to perform necessary adjustments sooner, reducing the overall waiting time while the main image can be generated later if required.
2Measurement precision
If the radiation image display apparatus performs complete image processing to generate a main image, then the image quality is improved, but the processing time and operational complexity increase
Solution Approach 1:
The patent segments the image processing workflow into preview generation and main image generation stages. The preview image is generated quickly using simplified processing, allowing fast display and adjustment. The main image with complete processing can be generated subsequently, separating the time-critical display function from the quality-critical processing function.
Solution Approach 2:
The patent performs preliminary action by generating a preview image before the main image processing is complete. This preview serves as a preliminary version that allows photographers to perform adjustments early in the workflow, rather than waiting for the complete main image processing to finish, thereby improving processing efficiency.
3Device complexity
If the radiation image display apparatus requires waiting for main image generation before allowing adjustments, then the processing workflow is simplified, but the ease of operation decreases
Solution Approach 1:
The patent segments the operational workflow into two independent phases: preview viewing/adjustment phase and main image generation phase. This segmentation allows photographers to perform adjustments during the preview phase without needing to wait for main image generation, improving ease of operation while keeping the overall system relatively simple.
Solution Approach 2:
The patent enables preliminary adjustments to be made on the preview image before the main image is fully processed. This preliminary action allows photographers to perform necessary operations early in the workflow, improving operational convenience without significantly complicating the overall system architecture.
